Abstract

Kreissägeblatt zur Reduzierung der Länge der zu langen Sägespäne mit ein bis maximal vier Höchstleistungszähnen mit vergrößerter Zahnhöhe und/oder vergrößerter Zahnteilung vor diesen Höchstleistungszähnen.Circular saw blade for reducing the length of too long sawdust with one to a maximum of four high performance teeth with increased tooth height and / or enlarged tooth pitch before these high performance teeth.

Description

Die bekannten Kreissägeblätter mit gleicher Zahnform und -teilung erzeugen insbesondere bei Doppelwellenmaschinen im Bereich des Schnittes parallel zur Holzfaser Späne, die durch ihre extreme Länge den Sägemehltransport stören.The known circular saw blades with the same tooth shape and division produce especially in double-shaft machines in the area of the cut parallel to the wood fiber shavings, the by their extreme length the sawdust transport to disturb.

Der Erfindung liegt die Aufgabe zugrunde, ein Sägeblatt zu schaffen, das die Länge dieser Späne deutlich reduziert.Of the Invention is the object of the invention to provide a saw blade, the Length of this Chips clearly reduced.

Das erfindungsgemässe Sägeblatt (1) weist eine Zähneanordnung auf, dergestalt, dass mindestens ein maximal vier Höchstleistungszähne (2) eine deutlich grössere Spandicke erzeugen als die übrigen Zähne dadurch, dass diese Höchstleistungszähne (2) auf einem grösseren Flugkreis liegen und/oder dass vor diesen Höchstleistungszähnen (2) eine vergrösserte Zahnteilung (t1) angeordnet ist.The saw blade according to the invention ( 1 ) has a teeth arrangement such that at least a maximum of four maximum power teeth ( 2 ) produce a significantly larger chip thickness than the other teeth in that these high-performance teeth ( 2 ) lie on a larger circle and / or that these high-performance teeth ( 2 ) an enlarged tooth pitch (t 1 ) is arranged.

1 zeigt die erfindungsgemässe Säge (1) mit zwei Höchstleistungszähnen (2) und der Zahnhöhendifferenz (ΔH) dadurch bewirkt, dass jeweils eine Hälfte der Säge einen anderen Radiusmittelpunkt hat als die andere, auf dem die Normalzähne (3) liegen. Zur Erhöhung des Vorschubs für den Höchstleistungszahn (2) ist vor diesem eine vergrösserte Zahnteilung (t1) im Vergleich zur zur normalen Zahnteilung (t2). 1 shows the saw according to the invention ( 1 ) with two high-performance teeth ( 2 ) and the tooth height difference (ΔH) is effected in that one half of the saw has a different radius center than the other, on which the normal teeth ( 3 ) lie. To increase the feed for the high-performance tooth ( 2 ) is in front of this an enlarged tooth pitch (t 1 ) compared to the normal tooth pitch (t 2 ).

2 zeigt die erfindungsgemässe Säge (1), bei der alle Zähne (2 und 3) auf dem gleichen Kreis liegen und die Mehrbelastung der Höchstleistungszähne (2) durch die vergrösserte Zahnteilung (t1) im Vergleich zur normalen Zahnteilung (t2) erzielbar ist. 2 shows the saw according to the invention ( 1 ), in which all teeth ( 2 and 3 ) lie on the same circle and the additional load of the high-performance teeth ( 2 ) is achieved by the enlarged tooth pitch (t 1 ) compared to the normal tooth pitch (t 2 ).

3 zeigt die erfindungsgemässe Säge (1) mit den um die Zahnhöhendifterenz (ΔH) erhöhten Höchstleistungszähnen (2) im Vergleich zu den normalen Zähnen (3) und der vergrösserten Zahnteilung (t1) bzw. der normalen Zahnteilung (t2). 3 shows the saw according to the invention ( 1 ) with the high-performance teeth (ΔH) increased by the tooth height ( 2 ) compared to the normal teeth ( 3 ) and the enlarged tooth pitch (t 1 ) or the normal tooth pitch (t 2 ).

Claims (1)

1) Kreissägeblatt dadurch gekennzeichnet, dass mindestens ein oder maximal vier Höchstleistungszähne (2) um die Zahnhöhendifferenz (ΔH) höher sind als die Normalzähne vor den Höchstleistungszähnen (3) oder dass alle Zähne auf dem gleichen Flugkreis liegen und eine vergrösserte Zahnteilung (t1) vor einem oder maximal vier Höchstleistungszähnen (2) angeordnet ist oder dass die Höchstleistungszähne (2) hinter der vergrösserten Zahnteilung (t1) um die Zahnhöhendifferenz (ΔH) erhöht sind bei einem oder maximal vier Zähnen und in einer Sonderausführung die Höchstleistungszähne (2) länger und/oder dicker sind und/oder aus einem weicheren Hartmetall, weicheren Stellit oder einem anderen weicheren Werkstoff bestehen. 1 ) Circular saw blade, characterized in that at least one or at most four high-performance teeth ( 2 ) to the tooth height difference (ΔH) are higher than the normal teeth before the high-performance teeth ( 3 ) or that all teeth lie on the same circle and an enlarged tooth pitch (t 1 ) in front of one or at most four high-performance teeth ( 2 ) or that the high-performance teeth ( 2 ) behind the enlarged tooth pitch (t 1 ) by the tooth height difference (ΔH) are increased in one or at most four teeth and in a special version, the high-performance teeth ( 2 ) are longer and / or thicker and / or consist of a softer hard metal, softer stellite or another softer material.
